Hydrocol Microparticle System Comes to Standard News Production, 2000 Papermakers Conference Proceedings
Thomas A. Cauley--Microparticle retention/drainage aid systems are used widely in the production of North American fine paper and board as well as in mechanical specialty grades including LWC and even SCA. North Americans however have not yet embraced this technology in the standard news sector. The main reason for this lies in the fact that in general the standard news furnish is too highly anionic of an environment for most micro particle systems to perform in cost effectively. This paper will detail the experience and benefits that were achieved by switching a gap-blade former using 100% DIP from a three polymer retention aid system to a micro-particle system.
